Abstract :The review first addresses the major bottleneck of conventional toxicity tests with invertebrates, namely the need for continuous culturing and/or maintenance of stocks of live test-organisms. Subsequently the history of the development and the validation of the first cyst-based microbiotests are outlined. Details are given of the large intercalibration exercises organized concurrently ...
